Glowing Lights Material

Hi everybody. Today I'm going to show you a glowing material, similar to neon lights.

There are several node setups here in BlenderArtist, but normally in the
reder I have seen a burn spot in this kind of materials. You can add a
glass effect to the material mixing the emission node with a glossy node
and a fresnel factor. Something like this:

Change the fresnel and roughness values to get different classes of
glass. Note that the emission strength value should be set up in
accordance with the rest of lights in the rendered scene (lamps or
meshlights). Therefore this value could be higher or lower in your
scene, depending on the values of the other lights.

In my test scene I have removed the top lights to highlight the glowing effect.
